MASSAGE-VIBRATOR.

Application filed August 26,

To all whom it may concern:

Be it known that l, Fnnnnniok Il. llamrmivn, a citizen of the United States. residing at New York, in the county o'l New York and State oil New York, have invented new and useful improvements in Massage Vibrators, of which the following is a speci- .lieation.

The present invention has reference to improvements in massage vibrators, and more especially in that type ol vibrator. which includes an applicator carried by a rocking lever. its object cmnprehends, gen erally, the production of a massage implement of the type specified wherein the construction is simplified and the elliciency increased to a maximum extent by the employment oil. as 'lew parts as possible to! etlecting the rocking movements ol the lever, and by rendering these parts certain and positive in their operation.

A structural embodiment of the invention is illustrated in the accompanying drawing, wherein Figure 1 is a longitudinal vertical sectional view of the improved vil'n'ator, taken on the line DD of Fig. 5. l ig. 2 is a transverse vertical sectional view taken on the line -C of Figs. 1 and Fig. 3 is a detail plan view Oil the star wheel which operates the applicator lever. Fig. 4 is a horizontal section taken on the line Ii--13 of Fig. 1. Fig. 5 is a horizontal sectional view taken on the line AA of Fig. 1,.

The casing of the implement, wherein the various working parts are arranged, comprises a tubular handle portion 1 terminating at its front end in a cuplike extension 2, and a hollow tapering neck or stem 3 formed at its upper end with a cup 4:, which is a counterpart of cup 2, above reterred to, the two cups being connected together by a series of bolts Between the cups 2 and t is interposed a horizontal partition plate 6 formed upon its upper face with a contrally located stepped bearing 7 and upon its lower face with a similarly located de- )ending sleeve 8, the bore of said sleeve opening through the upper end of the hearing 7. The sleeve 8 constitutes a support for the vertical shaft 9 of a water wheel 10, the stepped central portion or hub 11 of said wheel fitting upon the stepped portion 7 of plate 6.

The water wheel, shown in Figs. 1. and

5, preterably comprises a series of arms 12 which radiate from the hub portion '11. and have their enlarged t'rec ends cupped, as imlicatcd by the numeral 13. \Vhile any prel'erred means may be utilized for elleeting the rotation oi the water wheel, as will be apparent, it, is considered advisable to employ a current oi water tor this purpose. Accordingly, the interior ol the handle portion 1 ot the casing is divided into two isolated watcr passages or conduits it and 15, shown in l igs. l, 52 and 5, the secoiul-named passage constituting the water inlet and being provided at its inner ends with an aperture ill through which the water is injected tangentially against the wheel cups. To form this aperture to, an opening is preterably drilled through the casing from the outside, the openin in the outer wall being subsequently closed by a screw 17 or other suitable plug. The lower end of the wheel shall 1) is reduced. as shown in Fig. l, and constitutes a spindle on which is threaded a multi-pointed member 18, preferably in the form ot a star wheel. Upon the upper three of? this wheel there is formed an annular flange ll) which [its against an annular shoulder 2!) formed upon the lower end of the bearing sleeve 8, the arrangtnnent being such that while the wheel shaft, when in motion, will rotate the star wheel the intercngagenlent ot the flange and shoulder will preclude upward movement and consequent displacement ot the water wheel and wheel shal't. During the rotation of the star wheel, its teeth are designed to suecessively strike against the nose 21. formed upon the enlarged head ol the applicator lever 23, thereby imparting the necessary rocking movements to the latter, as hereinafter described. in its preferred form, this lever con'iprises an angular metal red, the two arms of which lie in di llerent planes, the upper arm terminating at its free end in the above mentioned head 22, and the lower arm in a threaded pin 2t, an enlargement or collar being formed at the upper end of the pin. To the lower end of said pin there allixcd the usual cup 26. The said lever is mounted adjacent its lower end in a diaphragm 97 constructed o'l rubber or other suitable elastic material and supported at. its peripheral edge lnrtween a circumferential shoulder formed on the inner surface of the neck 3 at the lower end thereof,

and the in-turned lower end 29 of a cap nut 30, which nut is threaded upon the neck end. The lever is fastened to this diaphragm by inserting its pin 24 through a central opening therein until the under face of the collar 25 rests upon the upper face of the diaphragm, after which a pair of nuts 31 and 32 are threaded upon said pin to clamp the diaphragm against the under face of said collar, the attachment of the cup 26 to the lever being effected subsequent to the positioning of the two clamping nuts, as will be understood.

Owing to the flexibility of the diaphragm, the desired rocking movements or vibrations may be imparted to the lever. To effect such movements, there is provided, in conjunction with the star wheel already described, a pair of springs 33 and 34, which are arranged at right angles to each other. Spring 33 is arranged in the vertical plane of the lever and has one end thereof received in a recess 35 formed in the head 22, the other end of said spring projecting into an opening 36 formed through the casing wall and closed by a plug 37. The spring 34, in like manner, is received at one end in an opening 38 formed through the casing wall at right angles to the opening 36, and bears at its opposite end against one side of head 22. See Fig. 4. Opening 38 is likewise closed by a plug 39 similar to the plug 37. The arrangement of the two springs 33 and 34 with respect to the head of the lever issuch that the first spring will tend to move said lever laterally inward toward the star wheel, while the second spring tends to normally impart a lateral movement to said lever at right angles to the first movement. Both springs bear continuously against the head of the lever, and, in consequence, hold said head at all times against the periphery of the star wheel. Consequently, when the star wheel is in motion, the successive contact of its teeth against the nose of said head will result in a compound vibratory movement of the lever, i. 0., the lever is vibrated laterally by two separate forces acting at right angles to each other, which movement is in turn imparted to the cup 26.

In order to prevent the escape of water from the upper cup into the lower cup, an annular washer 40 is interposed between the adjacent edges of the cup 2 and the partition plate 6, the latter element being formed upon opposite sides with circumferential flanges 41, which facilitate its correct positioning with respect to the cups 2 and 4. The upper of the two flanges also assists in preventing the escape of the water from the upper cup. Additional annular washers 42 and 43 are also interposed between the adjacent faces of the stepped hub 11 and the stepped bearing 7.

In order to provide for the admission of air into the interior of the casing, when the water wheel is in motion, the upper wall of said casing is provided with a vent 44 located directly above the wheel shaft and normally closed by a ball valve 45 movable in a tubular boss 46. Said boss is likewise formed integral with the casing wall and depends therefrom. It is of suflicient eX- tent to receive a coil spring 47, which presses the ball upward against the vent, the lower end of the spring bearing against a cross pin 48 inserted in said boss.

The operation of the implement is believed to be apparent from the foregoing, and further description thereof is accordingly omitted,

I claim as my invention:
